The unique watch with mechanical 'digital' display

Apr 18, 2008

If you consider that Di Grisogono Meccanica DG is a hybrid mechanical-digital watch, then you are wrong. This is a limited-edition line of the watch that includes just 177 amazing models.

It is remarkable, that the watch consists of 651 pieces and there are no digital parts or LEDs. The gadget was presented as the world's most complicated digital-analog watch. Anyway, the digital display is mechanical and is made of rolling tubes that form the digital segments.

This is the description of the work of the watch:
The gadget's digital display is mechanically operated, it shows tens of hours, single hours, tens of minutes and, of course, single minutes. The whole system is displayed via mobile micro segments driven by an accumulation of 23 cams attached to a set of gears and a starting and synchronization system. The necessary information about the time is showed by a system of 23 horizontally and vertically positioned micro segments.

The horizontal segments are 2.90 mm in length and their weigh is just 10 milligrams. At the same time, vertical segments measure 9 mm high, but the weight is 25 milligrams. The segments feature four sides: two opposing visible sides featuring multicolored strips and the other sides are unmarked. Time changes depend on 90 rotations of the segments.
